RISC-V: Fix opcode entries of "vmsge{,u}.vx"
Their check_func should be "match_never", not "match_opcode". The reasons
this error did not cause any disassembler errors are:
1. The problem will not reproduce if "no-aliases" is specified
(because macro instructions are handled as aliases).
2. If not, all affected compressed instructions or their aliases
precede before "vmsge{,u}.vx" macro instructions.
However, it'll easily break if we reorder opcode entries. This commit
fixes this issue before the *accident* occurs.
opcodes/ChangeLog:
* riscv-opc.c (riscv_opcodes): Make sure that we never match to
vmsge{,u}.vx instructions unless specified in the assembler.
